Question

What is the output of the given code?

counter = 1
while counter < 11
  puts counter
  counter = counter + 1
end

counter = 1: Initializes a variable counter with the value 1.
while counter < 11: This is the loop condition. The code inside the loop will execute as long as the value of counter is less than 11.
puts counter: This line prints the current value of counter to the console.
counter = counter + 1: This line increments the counter by 1 in each iteration.

Now, let's trace the execution:

Iteration 1: counter is 1. 1 < 11 is true. puts 1. counter becomes 2.
Iteration 2: counter is 2. 2 < 11 is true. puts 2. counter becomes 3.
...
Iteration 10: counter is 10. 10 < 11 is true. puts 10. counter becomes 11.
Iteration 11: counter is 11. 11 < 11 is false. The loop terminates.
